Custom Resolution Utility (CRU)

[SoyaBean]

Hello, may I know if its possible to get 1920x1080 144Hz at 300Mhz ?

My current settings in CRU which the only highest I can get is 1920x1080 136Hz at 300.99Mhz which I cannot go more than 300.99Mhz because new resolution doesnt show above 300.99Mhz


Laptop :
Lenovo Ideapad 330 15ICH i5 8300H + GTX1050
HDMI 1.4a

External Monitor :
Acer Nitro XV240Y P 165Hz
HDMI 2.0

Hi OP,
Many thanks for developing this wonderful utility .
I was wondering if it’s possible to make 1080 P content look correct on 4K displays. My computer has a very old graphic card that only supports 1080 P resolution. when connected it to a 4K display the content to look even more fuzzy then on 1080 P displays

You shouldn't have to, but NVIDIA's driver has bugs with Surround and EDID overrides.

Intel GPUs don't support more than 300.99 MHz. The only thing you can do is reduce the totals as low as the monitor will allow.

Try with and without GPU scaling.

Does anyone know if a Samsung NU6900 TV (43 inch if it matters) can be pushed to >60hz effectively with this? I've attempted it, but if if the TV is capable of it I believe the bottleneck was the cable I use to go from my PC to my living room TV, which is about 50 feet. I managed to get a picture to the TV, but if I remember right the image did not fill the screen.

The NU6900 range is a fairly budget line of 4k TVs but if I could squeeze 1080p and 100+ frames out of it that would be cool. I tried searching and skimming the thread to no avail.

Hi ToastyX,

I have problems with CRU. I have an LG 24MP59G-P FreeSync monitor and RTX2060 videocard. I turned on freesync in the monitor settings and turned on g-sync in nvidia control panel. I have 1-2 seconds black screen when fps drops down, sometimes monitor goes black even if the FPS is stable. So thats why I tried to change the freesync range from 40-75 to 41-75 with CRU. Before doing this I turned off freesync on the monitor then I applied the new freesync range in CRU, then when I went to the monitor settings and turned on freesync, the monitor went completely black. At this time I can reach the monitor settings (OSD) but even if I turn freesync off, I can't get back the display. So I needed to push the power button 5-6 seconds long to turn off the computer then I needed to turn it on to have the monitor back. What should I do now to change the freesync range? Maybe Do I need to enable freesync while change the range is CRU? Or what didn't I pay enough attention to?

Thanks is advance,
Peter

pixel clock is limited to 655.359 mhz, is there anyway to go above that?

Create DisplayID extension block. Then create timing there.
